You may check the collinearity of the given points using the following determinant formula, such that:

`Delta = [(4,2,1),(3,3,1),(2,4,1)]`

You need to notice that each of the three rows of determinant contains the coordinates of the given points. Since the problem provides two coordinates points, the last position, on each row, is filled in with 1.

You need to evaluate the determinant, such that:

`Delta = [(4,2,1),(3,3,1),(2,4,1)]`

`Delta = 12 + 12 + 4 - 6 - 16 - 6 = 0`

Since `Delta = 0` yields that the given points are collinear.

Hence, testing the collinearity of the given points, using determinant formula, yields that the points are collinear.
